Debian DSA-2304-1 : squid3 - buffer overflow

medium Nessus Plugin ID 56143

Synopsis

The remote Debian host is missing a security-related update.

Description

Ben Hawkes discovered that Squid 3, a full featured Web Proxy cache (HTTP proxy), is vulnerable to a buffer overflow when processing Gopher server replies. An attacker can exploit this flaw by connecting to a Gopher server that returns lines longer than 4096 bytes. This may result in denial of service conditions (daemon crash) or the possibly the execution of arbitrary code with rights of the squid daemon.

Solution

Upgrade the squid3 packages.

For the oldstable distribution (lenny), this problem has been fixed in version 3.0.STABLE8-3+lenny5.

For the stable distribution (squeeze), this problem has been fixed in version 3.1.6-1.2+squeeze1.
